Title :ポリアクリルアミド含水ゲルのゲル化にともなう散乱光強度の変化
Authors :大崎 知惠
Issue Date :Feb-2011
Abstract :The gelation process of the polyacrylamide hydrogel is investigated. Some properties of the solvent in gels are very similar to those of the solvent in free solution,but some properties are not. The author is interested in the similarities and the differences between these two states,gel and solution,and have investigated some properties of gels and pre-gel solutions. When the molecular structures of polyacrylamide hydrogels during gelation reaction were investigated by means of Raman scattering, the change of intensity not owing to the molecular structure was observed. The author investigates the intensity changes of Rayleigh scattering light which may occur during the gelation process. He-Ne laser, Ar􌚸ion laser, or halogen lamp are used as the light source, and the scattering light is monitored by the small spectrophotometer with CCD. The intensity of scattering light increases abruptly after some duration time. It is suggested that the abrupt increase coincides with the gelation or polymer network formation. The intensity of Rayleigh scattering light increases abruptly owing to the abrupt change of the microstructure of the solution.
